BOSTON — A Boston University student organization is calling on the school to cancel an upcoming concert by Robin Thicke over what it calls the singer’s sexist lyrics, but school officials say that is unlikely.

By Thursday, about 1,400 people had signed an online petition started by the Humanists of Boston University.

The petition says, “It is a dishonor to our feminist history to symbolically idolize Robin Thicke by allowing him to perform his misogynist music at our university,” and that Thicke’s hit song, “Blurred Lines,” “celebrates having sex with women against their will.”

A university spokesman says the March 4 show at Agganis Arena is unlikely to be canceled and the school’s administration played no role in booking it.

National Park Service spokeswoman Christie Van-over said Thursday that investigators traced the Oct. 18 sinking of the 65-foot vessel at a Lake Mead marina to the failure of two hoses to drain water from a rear storage compartment.

Vanover says one hose was disabled by a kink. Another wasn’t properly connected.

No one was on the boat and no one was injured when the 1996 Skipperliner, named Rendezvous, sank stern-first in 45 feet of water in a slip at the Temple Bar marina.

She had said that Newton and his wife were vacationing out of the country when the boat sank.

WASHINGTON — A man who says he was punched in the face by singer Chris Brown and his bodyguard during an altercation outside a Washington hotel is suing for $3 million.

The civil lawsuit filed Tuesday in Superior Court in Washington seeks $1.5 million from each man. The lawsuit filed by lawyers for Parker Isaac Adams says that Adams’ nose was fractured and he had other injuries to his head and face as a result of being punched.

Adams said in a telephone interview Thursday that he is seeking to recover money for his medical bills which include visits to a plastic surgeon and a breathing specialist. The lawsuit seeks compensatory damages of $1 million and punitive damages of $500,000 from each man. A lawyer for Adams, John C. Hayes Jr., said his client is largely seeking money for “pain and suffering” though he is continuing to receive medical care for his injuries.

Brown and his bodyguard, Christopher Hollosy, were arrested in October after Adams said both punched him in the face outside the W Hotel. The lawsuit says Adams, 20, tried to get in a picture that Brown was taking with two of Adams’ friends, and the singer and then Hollosy punched him.

Lawyers for Brown and Hollosy declined to comment Thursday on the civil lawsuit.

At the time Brown was arrested, the Grammy winner was on probation in California for a 2009 attack on singer Rihanna, his then-girlfriend.

Both Brown and Hollosy are charged criminally in Washington with misdemeanor assault, and the result of the case could affect Brown’s case in California.

During a hearing Thursday, lawyers picked April 17 as the start date for the trial for the two men. Lawyers said they expect the trial will last two or three days. Neither man was present for the hearing.

NEW YORK — A former money manager to celebrities including Leonardo DiCaprio and Ben Affleck has been arrested again on fraud charges.

It’s been more than a decade since Dana Gia-cchetto was convicted of bilking his Hollywood clients. He was released on $150,000 bail Thursday after appearing in federal court in Manhattan.

A criminal complaint accuses him of using someone else’s credit card to make purchases of more than $10,000 a year ago in New York. Giacchetto’s lawyer said his client denies the charges.

The complaint says Giacchetto is now the owner of a gourmet canned food company called “Taste.”

In the earlier case, Giacchetto pleaded guilty to charges that he squandered nearly $10 million of his Hollywood clients’ funds on a lavish, drug-abusing lifestyle. He received a nearly five-year prison term.
